The neutrals for the cities can probably lowered. 5 neutrals on a map this small almost guarantees they will never be taken even as part of the bonus.
Is there a reason why N. Afar starts as neutral? Is this for the golden number? If so, I would suggest making it a region with less importance as far as moving across the map...a region like SSW Oromia, SBG, or NBG.
As far as the bonuses are concerned, they all look good, but you might think about increasing the bonus for the continent that contains DIre Dawa to a +4 and the continent that contains N. Afar to a +3.
